26、It’s a popular belief that a fish’s memory lasts for only seven seconds. It may seem sad to think that they don’t remember what they’ve eaten or where they’ve been, and they don’t recognize you or any of their friends — every moment in their life would be like seeing the world for the first time.
But don’t be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago.
In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again.
Researchers used computer software to monitor the fish’s movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.
In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively(挑衅地) in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.
Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild.
“If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.
For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.
【1】What is the article mainly about?
A. Fish having very bad memories.
B. Fish being smarter than we thought.
C. How fish improve their memory.
D. What we can learn from fish.
【2】According to the article, people used to believe that _______.
A. fish could only remember part of their past experiences
B. fish could remember things that happened 12 days ago
C. a fish’s memory lasted for only seven minutes
D. fish didn’t recognize any of their friends
【3】How can fish benefit most from a good memory? They can remember _______.
A. where to get food and survive
B. their enemies and fight
C. where to escape to when in danger
D. their friends and help each other
【4】Which of the following is TRUE according to the passage?
A. Fish behave aggressively in a fight.
B. Fish can remember more.
C. Fish don’t belong to the list of smart animals.
D. Only African cichlids have a good memory.
27、When it comes to US middle school science and engineering, girls rule. Girls took the top five prizes at the 2019 Broadcom MASTERS, a competition for middle school students across the country.
The winners were announced (宣布)last month. They were honored for their STEM successes as well as for showing skills in critical thinking, communication, creativity and team-work. In first place was 14-year-old Alaina Gassler. She designed a system to make driving safer by reducing blind spots-the areas that drivers cannot see outside their vehicle (车辆)Gassler developed the technology while in eighth grade.
“She, along with the entire Class of 2019, is already leaders in their fields of science, technology, engineering and mathematics (STEM),” said Paula Golden, president of the Broadcom Foundation. “These young inventors give every one of us hope for the future.”
The Broadcom MASTERS competition is a project of the Society for Science & the Public. It was set up to encourage young people to attend college and take up jobs in STEM fields. It was open to students in grades 6, 7 and 8 across the country.
This year, all the major awards in the competition went to girls. The top prize winner, Alaina Gassler, says she got the idea for her project after seeing her mother struggle with blind spots in her family’s car. Blind spots lead to many accidents—about 840, 000 accidents a year nationwide.
Gassler’s system helps drivers see “through” the A-frame pillar (A柱)—the part of the vehicle, in the front, that joins the top and front window. The A-frame pillar is important for safety, and cannot be removed. Gassler used a camera to help drivers look “through” the structure (结构)to see what is blocked. The camera sends video to a device (设备)that shows images on the other side of the pillar. The driver then can “see” what’s in the blind spot.
The young inventor won a $ 25, 000 prize for her invention. She told Popular Mechanics she can make improvements on her device with that money. Gassler said she wants to improve the picture—making it easy to see in any weather, or any time of the day. She also told the magazine she hopes to sell her idea.
【1】Why was Gassler honored?
A.For her interest in science.
B.For her great concern.
C.For her vehicle knowledge.
D.For her STEM success.
【2】What does the underlined sentence in paragraph 5 actually suggest?
A.The reasons why the mother struggled.
B.The great need of STEM education.
C.The great value of Gassler’s invention.
D.The poor quality of family vehicles.
【3】What is paragraph 6 mainly about?
A.How Gassler’s system works.
B.Why the A-frame pillar is important.
C.When Gassler’s system helps.
D.What are included in her inventions.
【4】What is the best title for the passage?
A.Young students’ great inventions
B.US students compete in science
C.Middle School STEM education
D.US girls take top science prizes
28、 Jim was a young man in his early twenties who was studying to be a carpenter. He was a good worker, honest and worthy of trust, so his boss was pleased with him. As he was such a likable man and easy to deal with, he was popular with his workmates, too. They also made fun of him a great deal but he never got angry with them and would only laugh.
But Jim’s one great shortcoming was that he could never tell a lie, no matter how hard he tried, not even a little one. In fact, he was so honest and shy that he would blush even when he was telling the truth. He used to stand in front of the mirror and practise lying while looking himself in the eyes at the same time. But as soon as he saw his face starting to go red he had to look away.
One morning, however, he didn’t feel like going to work because he had been to a party the night before and it hadn’t ended till the early hours of the morning. And so far the first time in his life he decided to take the day off. He rang his boss, pretending to be a woman. “I’m afraid Jim can’t come to work today. He isn’t feeling very well.”
Poor Jim was thankful that his boss couldn’t see him just at that moment because his hands were trembling(发抖) and his face was bright red.
“Thank you for letting me know,” said Mr. Woods, his boss, and then just as he was about to hang up, he said, “just a moment, madam, who’s speaking.”
“Oh!” he stammered (口吃的说), and going all out for making a voice like a woman, he cried in a voice: “This is my landlady speaking!”
【1】According to the passage we know that Jim was a ___.
A.skillful worker
B.skillful carpenter
C.researcher studying how to be a carpenter
D.being-trained carpenter
【2】What does the underlined word “blush” in Paragraph 2 probably mean?
A.stammer B.look away
C.go red D.feel hot
【3】Why did Jim try to practise lying?
A.To avoid being laughed at by his workmates.
B.To overcome his shortcoming.
C.To get his boss pleased with him.
D.To get ready for asking for leave.
【4】At the end of the story poor Jim let the cat ____.
A.out of the bag B.out of the house
C.into the bag D.into the house
29、Playgrounds for All Kids
Most of us are all too familiar with the typical playground set-up, monkey bars, swings, and slides, all accessed by steps and surrounded by a sea of sand or wood chips. 【1】 However, many disabled children end up being unable to access all of the equipment because of the way it’s constructed.
【2】Its founder, Cody Goldberg, wanted to build a place for his disabled daughter Harper to play freely. It uses spiral(螺旋形的) walkways leading to activities, rather than steps, where kids in wheelchairs ride alongside those on skateboards. 【3】 Play areas are accessible to both wheelchair users and walkers.
Goldberg describes the idea behind designing these playgrounds as completely inclusive. They don’t strictly cater to (迎合) children with disabilities and are not meant to prevent any child from having access to play.【4】The inclusive playground model is now spreading across the county. While the original Harper’s Playground is located in Portland, Oregon, similar playgrounds have popped up throughout the state. Harper’s Playground is now teaming up with those interested in building a park of their own. 【5】 Changing the way playgrounds are built will have a wide-spread effect. It will affect the way schools are designed and built, and it will affect how the workplace is treated, and then ultimately it will change the way people with disabilities are thought of and treated.
A.What are their accessible playgrounds like today?
B.Harper’s Playground was created for just this problem.
C.Harper’s Playground began to work on its initial designs.
D.The equipment and layout provide access to a fun experience for all.
E.Slides are built extra wide so a caregiver and a child can go together.
F.It hopes to eventually spread across the country and, ultimately, the world.
G.The intention of these public playgrounds is to give kids a safe and fun place to play.
